An international team of scientists led by João Passos at Newcastle University has for the first time shown that mitochondria (the “batteries” of the cells) are major triggers for aging, and eliminating them upon the induction of senescence prevents senescence in the aging mouse liver.

As we grow old, cells in our bodies accumulate different types of damage and have increased inflammation, factors that are thought to contribute… read more

A Drexel University materials scientist has discovered a way to encapsulate medication to deliver it more effectively inside the body.

Until now, crystals have grown in rigid, structured formations (like the snowflake) — with a web of straight lines connecting to making a grid that grows into the crystalline flake.*

But the formation of a crystal is affected by the environment in which it forms. And Christopher… read more

Researchers at Mayo Clinic have discovered that senescent cells — cells that no longer divide and accumulate with age — shorten lifespan by as much as 35 percent in normal mice.

Removing these aging cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects, the researchers found, writing Feb. 3 in Nature.

“Cellular senescence is a biological mechanism that functions as… read more
